I'm using zielmicha's Emacs for Android to run Emacs on my smartphone. It works well overall, but I have to set my font size really small to prevent Emacs from crashing on startup. No config files here, just emacs -Q. Trace: $ emacs -Q -------------------------------------------------------------------------------------------------------------------------------------------- Fatal error (11) emacs: line 2: 10243 Segmentation fault /data/data/com.zielm.emacs/src/bootstrap-emacs $@ But the problem is not just having enough screen size for Emacs: If I shrink my onscreen keyboard vertically below 45% of the screen, Emacs crashes. It seems that Emacs not only needs enough screen space, it needs just the right amount and no more. Can someone take a look at Emacs for Android (source on Google Code )?
